Airport Gravel Pit

Location: Approximately 1.5 mi E of Ambler.
Access: Via a two-mile-long road that passes near the airport, at Section 29, NW 1/4, T20N, R5E Kateel River Meridian (KRM).
GPS Coordinates:  N67°6’20.76?, W157°50’12.23?.
Material: Unconsolidated gravel with thick discontinuous lenses of sand.
Size Distribution: Estimated at 95% < 2”, 85% <1.5”, with occasional rounded cobbles up to 5”. Individual gravel units show distinct graded bedding.


The material at this site contains levels of naturally-occurring asbestos (NOA) that resulted in the site being closed in 2003. In 2012, the State of Alaska Legislature enacted House Bill 258, which provided users immunity against claims arising from the use of NOA gravel.


In addition to NANA gravel request requirements, the State of Alaska Department of Transportation & Public Facilities (ADOT&PF) regulates the use of NOA material. Therefore, ADOT&PF should be contacted before planning to use NOA gravel. 


For more information about NOA Gravel regulations, please contact the ADOT&PF or visit the NOA Program web page.
